The rate at which work is being done is called:
Correct answer: A. Power
- A. Power
- B. Energy
- C. Density
- D. Force
Explanation
The rate at which work is done is called power. It is expressed as the amount of work per unit of time.

About Work and Energy
Work transfers energy when a force causes displacement, while kinetic energy, gravitational potential energy and power describe motion, position and the rate of energy transfer. The work-energy theorem links net work with change in kinetic energy, and efficiency accounts for energy losses rather than treating them as energy destruction.
